That was my first job interview, I was studying in my final year. I got mail from HR, and I went to them. Firstly I had an interview with HR and that with Java Team Leader. Everything was great, but in the mail, I got firstly HR didn't mention that I will have an interview with Java Team Leader, so I didn't prepare for it. So I was horrible. In a couple of weeks, I got an email, where HR explains to me why I didn't get an offer.
